Jumpstart Jamstack Development

By: Christopher Pecoraro, Vincenzo Gambino

Overview of this book

Jamstack (JavaScript, API, and Markup) enables web developers to create and publish modern and maintainable websites and web apps focused on speed, security, and accessibility by using tools such as Gatsby, Sanity, and Netlify. Developers working with Jamstack will be able to put their knowledge to good use with this practical guide to static site generation and content management. This Jamstack book takes a hands-on approach to implementation and related methodologies that will have you up and running with modern web development in no time. Complete with step-by-step explanations of essential concepts, practical examples, and self-assessment questions, you'll begin by building an event and venue schema structure, and then expand the functionality, exploring all that the Jamstack has to offer. You’ll learn how an example Jamstack is built, build structured content using Sanity to create a schema, use GraphQL to expose the content, and employ Gatsby to build an event website using page and template components and Tailwind CSS Framework. Lastly, you’ll deploy the website to both, a Netlify server and the Microsoft Static Web Apps Service, and interact with it using Amazon Alexa. By the end of this book, you'll have gained the knowledge and skills you need to install, configure, build, extend, and deploy a simple events website using Jamstack.

GraphQL playground basics

In Chapter 5, SSanity's GROQ Language, in the Installing Vision section, Sanity's Vision tool was used to test the GROQ queries. Likewise, Sanity uses the GraphQL playground so that we can test GraphQL and interact with its datasets.

The GraphQL playground allows users to create and run GraphQL queries that can later be used to obtain information from a GraphQL API. In the following section, we will learn about its basic functionality.

The following is a screenshot of the GraphQL playground:

The GraphQL playground's interface is easy to use. Similar to the Vision GROQ tool, the queries are typed into the left-side window and are executed by clicking on the play icon in the middle of the interface.

As expected, the GraphQL results are displayed in the right window. Query variables may be entered into a bottom window.

On the right, there is a green-colored tab, labeled...
